2011-04-29ethtool: cosmetic: Use ethtool ethtool_cmd_speed APIDavid Decotigny
This updates the network drivers so that they don't access the ethtool_cmd::speed field directly, but use ethtool_cmd_speed() instead. For most of the drivers, these changes are purely cosmetic and don't fix any problem, such as for those 1GbE/10GbE drivers that indirectly call their own ethtool get_settings()/mii_ethtool_gset(). The changes are meant to enforce code consistency and provide robustness with future larger throughputs, at the expense of a few CPU cycles for each ethtool operation. All drivers compiled with make allyesconfig ion x86_64 have been updated.

2011-04-14ethtool: allow custom interval for physical identificationAllan, Bruce W
When physical identification of an adapter is done by toggling the mechanism on and off through software utilizing the set_phys_id operation, it is done with a fixed duration for both on and off states. Some drivers may want to set a custom duration for the on/off intervals. This patch changes the API so the return code from the driver's entry point when it is called with ETHTOOL_ID_ACTIVE can specify the frequency at which to cycle the on/off states, and updates the drivers that have already been converted to use the new set_phys_id and use the synchronous method for identifying an adapter. The physical identification frequency set in the updated drivers is based on how it was done prior to the introduction of set_phys_id. Compile tested only. Also fixes a compiler warning in sfc. v2: drivers do not return -EINVAL for ETHOOL_ID_ACTIVE v3: fold patchset into single patch and cleanup per Ben's feedback Signed-off-by: Bruce Allan <bruce.w.allan@intel.com> Cc: Ben Hutchings <bhutchings@solarflare.com> Cc: Sathya Perla <sathya.perla@emulex.com> Cc: Subbu Seetharaman <subbu.seetharaman@emulex.com> Cc: Ajit Khaparde <ajit.khaparde@emulex.com> Cc: Michael Chan <mchan@broadcom.com> Cc: Eilon Greenstein <eilong@broadcom.com> Cc: Divy Le Ray <divy@chelsio.com> Cc: Don Fry <pcnet32@frontier.com> Cc: Jon Mason <jdmason@kudzu.us> Cc: Solarflare linux maintainers <linux-net-drivers@solarflare.com> Cc: Steve Hodgson <shodgson@solarflare.com> Cc: Stephen Hemminger <shemminger@linux-foundation.org> Cc: Matt Carlson <mcarlson@broadcom.com> Acked-by: Jon Mason <jdmason@kudzu.us> Acked-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

2011-03-28cxgb3: Apply interrupt coalescing settings to all queuesAnton Blanchard
While testing the performance of different receive interrupt coalescing settings on a single stream TCP benchmark, I noticed two very different results. With rx-usecs=50, most of the time a connection would hit 8280 Mbps but once in a while it would hit 9330 Mbps. It turns out we are only applying the interrupt coalescing settings to the first queue and whenever the rx hash would direct us onto that queue we ran faster. With this patch applied and rx-usecs=50, I get 9330 Mbps consistently. Signed-off-by: Anton Blanchard <anton@samba.org> Acked-by: Divy Le Ray <divy@chelsio.com> Signed-off-by: David S.

2010-12-12drivers/net: don't use flush_scheduled_work()Tejun Heo
flush_scheduled_work() is on its way out. This patch contains simple conversions to replace flush_scheduled_work() usage with direct cancels and flushes. Directly cancel the used works on driver detach and flush them in other cases. The conversions are mostly straight forward and the only dangers are, * Forgetting to cancel/flush one or more used works. * Cancelling when a work should be flushed (ie. the work must be executed once scheduled whether the driver is detaching or not). I've gone over the changes multiple times but it would be much appreciated if you can review with the above points in mind. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: "David S.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

2010-02-24RDMA/cxgb3: Doorbell overflow avoidance and recoverySteve Wise
T3 hardware doorbell FIFO overflows can cause application stalls due to lost doorbell ring events. This has been seen when running large NP IMB alltoall MPI jobs. The T3 hardware supports an xon/xoff-type flow control mechanism to help avoid overflowing the HW doorbell FIFO. This patch uses these interrupts to disable RDMA QP doorbell rings when we near an overflow condition, and then turn them back on (and ring all the active QP doorbells) when when the doorbell FIFO empties out. In addition if an doorbell ring is dropped by the hardware, the code will now recover. Design: cxgb3: - enable these DB interrupts - in the interrupt handler, schedule work tasks to call the ULPs event handlers with the new events. - ring all the qset txqs when an overflow is detected. iw_cxgb3: - disable db ringing on all active qps when we get the DB_FULL event - enable db ringing on all active qps and ring all active dbs when we get the DB_EMPTY event - On DB_DROP event: - disable db rings in the event handler - delay-schedule a work task which rings and enables the dbs on all active qps. - in post_send and post_recv logic, don't ring the db if it's disabled.

2009-07-09cxgb3: Fix crash caused by stashing wrong netdev_queueRoland Dreier
Commit c3a8c5b6 ("cxgb3: move away from LLTX") exposed a bug in how cxgb3 looks up the netdev_queue it stashes away in a qset during initialization. For multiport devices, the TX queue index it uses is offset by the first_qset index of each port. This leads to a crash once LLTX is removed, since hard_start_xmit is called with one TX queue lock held, while the TX reclaim timer task grabs a different (wrong) TX queue lock when it frees skbs. Fix this by removing the first_qset offset used to look up the TX queue passed into t3_sge_alloc_qset() from setup_sge_qsets().

2009-05-29cxgb3: link fault fixesDivy Le Ray
Do not call t3_link_fault() under spinlock, as it calls msleep(). Besides, only the access to pi->link_fault needs to be serialized. Also initialize local variables before checking the link status, link state fields might otherwise end up containing garbage. Signed-off-by: Divy Le Ray <divy@chelsio.com> Signed-off-by: David S.

2009-04-20cxgb3: Fix EEH final recovery attemptDivy Le Ray
EEH attempts to recover up 6 times. The last attempt leaves all the ports and adapter down.hen The driver is then unloaded, bringing the adapter down again unconditionally. The unload will hang. Check if the adapter is already down before trying to bring it down again. Signed-off-by: Divy Le Ray <divy@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-04-20cxgb3: fix workqueue flush issuesDivy Le Ray
The fatal error task can be scheduled while processing an offload packet in NAPI context when the connection handle is bogus. this can race with the ports being brought down and the cxgb3 workqueue being flushed. Stop napi processing before flushing the work queue. The ULP drivers (iSCSI, iWARP) might also schedule a task on keventd_wk while releasing a connection handle (cxgb3_offload.c::cxgb3_queue_tid_release()). The driver however does not flush any work on keventd_wq while being unloaded. This patch also fixes this. Also call cancel_delayed_work_sync in place of the the deprecated cancel_rearming_delayed_workqueue. Signed-off-by: Divy Le Ray <divy@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-04-20cxgb3: fix link fault handlingDivy Le Ray
Use the existing periodic task to handle link faults. The link fault interrupt handler is also called in work queue context, which is wrong and might cause potential deadlocks. Signed-off-by: Divy Le Ray <divy@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
